DOOR FOR HOPPER CARS.

Application filed May 8,

This invention relates to hopper cars and more particularly to hopper cars having hoppers closed by doors meeting along the center line of the hopper opening and it is an ooject of this invention to provide a sectional door for a car of the class described and to so supportthe door that it may be more readily operated to dump the load than doors now in use and vhich will provide the maximum discharge opening without the door contacting with the rail.

the drawings:

1 is a fragmentary side elevation showing a portion of a car hopper proyided with doors constructed and supported in accordance with this invention, some parts being broken away to show other parts more clearly;

Fig. 2 is a partial horizontal section taken 9 on the line 22 of Fig. 1;

' F 3 is a partial vertical section taken on the line 33 of Fig. 1, some parts being brokenaway to show other parts more clearly;

Fig. l is a fragmentary horizontal section through the hinges which unite the door sections taken as on the line l-lof Fig. 3;

Fig. 5 is a fragmentary elevation showing the connection of the supporting arm to the outer edge portion ofthe outer door section;

Fig. 6 is a vertical section taken on the line 66 of Fig. 5; and

Fig. 7 is a fragmentary vertical section taken on the line 7- of Fig. 3.

In the dra which show but a portion only of a hop car body of the type having a single centrally di charging hopper, the bony l is carried by suitable underfranic having draft sills 2 and side sills l comprising spaced channel members. Mounted in beliriiigs in the side sills l and in a casting 5 secured to the hopper end slope sheet 7 and draft sills 2. is a door operating shaft 6 upon which a s i set S is keyed between the side sill members, the sprocket 8 being connected 1 suitable means, as chain 10, to an operaine: means (not shown). The inner end of the shaft 6 operativcly engages with one of a pair of cranks 12 journaled in the casting 5 and carrying a yoke 14 to which the upper ends of th door operatin rods 16 are pivotally connected. The loy. er ends of the rods 16 are provided with yokes 18 in which pivot pins 20 secure the upper ends of short links 7 22. the lower ends of which are connected by pivot pin 2% to the projecting end of a flange 1928. Serial No. 276,079.

channel 26 which extends along the free edge of the door 28 and is secured to the uiu or s de thereof. The pins 20 and 2% are placed t right angles to each other to insure freedom of movement of the door.

Each door 28 comprises an outer section 30 and an inner section 32 joined by hinges The outer door section 30 comprises a door plate 36 having a downwardly extending flange '38 along its outer edge and sti e ed by braces 40 attached to the under side thereof. To the outer edge of the door section 30 are attached'ears 42 to which pins 44 pivotally connect the lower ends of links 46 the upper ends of which are pivotally mounted in ears 48 attached to the hopper side slope sheet 50. The links 46 are of such length that when the door 28 is in closed position the door plate 36 lies close to the bottom ed e of the hopper side slope sheet 50. Extending longitudinal 1y of the door section 30 adjacent the inner edge thereof is an angle 52 which abuts the ends of the braces 40 and to which hinge butts 5-l are attached.

The door section 32 comprises a door plate 56 having aflange at its free edge against which the channel 26 abuts and angles 58 at tached to the upper surface along the side ed es of the plate and arranged with a flange projecting downwardly. Extending longitudinally ofthe door section 32 adjacent its outer edge is angle 60 secured to the underside ,of the door plate and to which the hinge butts .62 areattached, Extending between the angle 60 and channel 26 are braces 64 which reinforce the door plate 56.

To each end slope sheet 7 there are secured brackets 66 to each of which brackets a pin 68 pivotally connects the upper end of an arm 70 of substantially an inverted Y-shape having one branch of its forked portion attached to the channel 26 adjacent the connection of the link thereto and the other branch of the forked portion connected to the eid hinges ill by tllQ hinge pins 7 which coin nectthe hinge butts 5-l and As shown in Fig. 3. the edge of the door plate 56 passes beneath the door plate 36 and is curved about the hinge axis as a center so as to maintain a tight joint between the door plates 36 and 56.

hen the door operating mechanism is operated to drop the door 28, the door section 32 is moved by arms 70 aboutthe pins 68 as center while the door section 30 has the inner lljll edge carried by the arms 70 and the outer edge guided by the links 46 causing the outer edge to move outwardly of. the car and upwardly while the inner edge moves substantially outwardly only and the inner edge of the door section 32 moves outwardly to a much greater extent than downwardly, thus providing the maximum discharge opening with a gravity operated door without danger of the door contacting with the running rails.

It will also be noted that the arms 7 0 provide additional supports for the door 28 thus reducing the load on the rods 16 and rendering easier the operation of the doors to dump the load. It is to be understood that the drawings herein are for illustrative purposes only and that various changes in the form and proportions of the device may be made within the scope of the appended claims Without departing from the spirit of the inven-' tion.

lVhat is claimed is; 1; In a dumping car, a dumping door comprising hingeldsections' and means supporting said door at the hinge and free edges thereof and at the meeting edges of said v prising hinged sections, means supporting said door at the hinge and free edges thereof and an arm of inverted Y-shape supporting said door at the free edge thereof and at the meeting" edges'of said sections.

4:- In a dumping car, a dumping door C'Omprising hinged sections and supporting means for said doors'comprising links attached to the hinge edge of said door and the car body, rods attached to the free edge of said door and the door operating mechanism greens? and arms attached to the end slope sheets and the meeting edges of said sections.

5. In a dumping car, a dumping door comprising hinged sections and supporting means for said doors comprising links attached to the hinge edge of said door and the car body, rods attached to the free edge of said door and the door operating mechanism, and arms of inverted Y-shape pivotally supported from the end slope sheets and having their forked ends connected to the meeting edges of said sections and the free edge of the door.

6. In adumping car, a dump door comprising hinged sections, rigid arms defining the movement of one of said sections, links cooperating with said arms to define the movement of the other ofv said sections and operating means connected to one of said sections.

7. In a dumping car, a dump door comprising inner and outer sections pivotally connected, rigid arms defining the movement of said inner section, links cooperating with said arms to define the movement of said outer section and operatin means connected to said inner section.

8. In a dump car, a dump door comprising inner and outer sections pivotally connected, bifurcated arms connected adjacent opposite edges of said inner section and delining the movement of said section, links cooperating with said arms to define the move ment of said outer section and operating means connected to said inner section.

9. In a dump car, a dump door comprising hinged sections, bifurcated arms connected adjacent opposite edges of one of said sections and defining the movement of said section, links cooperating with said arms to define the movement of the other ofsai'd sections and operating means connected to one of said sections. 1

In witness whereof I have hereunto set my hand.
